CPT 61737 Medicare rate and RVUs

Contracted rate: % of Medicare Copy link

Commercial contracts are often written as a percentage of Medicare ("115% of Medicare"). Enter yours to see what it means for 61737. A contract benchmarked to the fee schedule applies it to your locality's allowed amount, not the $1,350.06 national baseline; the calculator finds that amount from your service ZIP.

Rates by locality Copy link

The national baseline uses GPCI 1.000. These locality-adjusted allowed amounts use each payment locality's own GPCIs. Select a state to see its localities.

Q4 2026 amounts, computed with each locality's own GPCIs, before the ~2% sequestration cut. A state with more than one payment locality shows a range—its tile is colored by the mean across those localities, which is a shading choice, not an amount anyone is paid.

How this amount is computed Copy link

CPT 61737 has a work RVU of 22.10, a non-facility practice expense RVU of 8.99, a facility practice expense RVU of 8.99 and a malpractice RVU of 9.33—for total non-facility RVUs of 40.42 and total facility RVUs of 40.42 in the Q4 2026 release.

The formula is: (work RVU × work GPCI + PE RVU × PE GPCI + MP RVU × MP GPCI) × conversion factor. National amounts use GPCI = 1.000. To price an RVU figure of your own, use the RVU-to-dollars converter.

Every rate combines three parts: work (the clinician’s time, skill and effort), practice expense (office overhead—higher when the service is done in a doctor’s own office), and malpractice (the share of liability-insurance cost). A blank means CMS publishes no national number for that part. Read it as unknown, never as zero.

Who’s billing it Copy link

Global period: what 61737's fee already covers Copy link

The fee covers pre-operative and post-operative work on the day of the procedure only—there is no follow-up window afterward. A visit the next day is separately payable.

A modifier reports what happened; it does not by itself make a service payable. Documentation has to support it.

Billing policy Copy link

These billing-policy indicators explain how 61737 is treated. They apply whether the code is nationally priced or carrier-priced: a restriction like "bilateral not allowed" still matters on a carrier-priced code. See modifier amounts below for the dollar figures these support.

Modifier amounts: -26/TC, -50, -80/81/82, -AS, -62, -66 Copy link

National Office (non-facility) amounts for the modifiers this code's indicators support. These are single-line modifiers only. -51 (multiple-procedure reduction) depends on the other codes on the same claim, so it's a claim-level number rather than a per-code one. Use the calculator for a locality-adjusted, sequestration-aware amount.

Not payable with 61737: -26/TC (professional/technical split); -62 (co-surgeons, each); -66 (team surgery).

Each amount applies a standard MPFS percentage (assistant surgeon 16%, non-physician assistant at surgery 13.6%, co-surgeon 62.5%, bilateral 150%) to the national Office (non-facility) amount above. CMS doesn't publish these as a column; Localis derives them, so check them against the current Medicare Claims Processing Manual before relying on them for payment. A row marked If documented carries the ordinary percentage, but this code's CMS indicator allows it only when documentation of medical necessity is submitted. Without that documentation, an unpaid claim is not an underpayment.

Modifier 59 and the X modifiers are not a universal bypass—CMS expects the most specific applicable modifier, and which one that is depends on the pair and the documented circumstances.

Payment review for 61737 Copy link

Four published payment rules can change what 61737 allows on a claim: facility-only practice-expense pricing, the same-day global package, the 150% bilateral adjustment and documentation-restricted assistant-at-surgery payment. Each is a legitimate reason for a paid amount to differ from the fee-schedule amount on this page.

Why 61737's rate changed Copy link

National baseline (GPCI 1.000) · Office (non-facility) · Before sequestration

61737's national amount rose $248.54 (+22.6%), from $1,101.52 in Q1 2022 to $1,350.06 in Q4 2026. Changes to the conversion factor, which CMS sets for every code, took $38.36 off. CMS revaluing 61737 itself added $286.90: +$221.10 from malpractice RVUs, +$84.84 from practice-expense RVUs and −$19.04 from work RVUs. The most recent change came in Q1 2026: −$74.80 (−5.2%), with −$102.54 from practice-expense RVUs, +$46.45 from the conversion factor, −$19.04 from work RVUs and +$0.33 from malpractice RVUs.

CMS doesn't publish this split; we derive it from each release's RVUs and conversion factor. We apply the new conversion factor to the earlier RVUs first, then price each RVU change at the new conversion factor. Another order would move a few cents between columns, but every total stays the same.

How often 61737 is billed Copy link

Across Original Medicare in CY2024, 61737 ranked #5,515 of the 7,879 CPT codes billed to Medicare that year, by patients served or total allowed dollars.

2024 Medicare fee-for-service national totals. They exclude Medicare Advantage, Medicaid and commercial volume, so real-world use runs higher. This is a calendar-year snapshot from the CMS Physician & Other Practitioners dataset, on a different cycle from the Q4 2026 fee schedule above.

How 61737 compares with other codes Copy link

Against every code with a national PFS amount in Q4 2026 · National baseline · Before sequestration

63.9% Highest vs. lowest locality

61737's Office amount is 63.9% higher in its highest-paid payment locality than in its lowest. That spread is wider than 92% of the 7,716 codes compared; the median spread is 43.6%. How much a code's amount varies by locality depends on its mix of work, practice-expense and malpractice RVUs, since each has its own GPCI.

These comparisons cover every code with a national Physician Fee Schedule amount: status A, R or T, with no blank RVUs. The locality comparison leaves out codes with an OPPS cap, because the cap, not the GPCIs, can set their amount in some localities.
